The reaction BrO+HO2→products is the
rate-limiting step in a key catalytic ozone destruction
cycle in the lower stratosphere. In this study a
discharge-flow reactor coupled with molecular beam mass
spectrometry has been used to study the BrO+HO2
reaction over the temperature range 233–348 K. Rate
constants were measured under pseudo-first-order conditions
in separate experiments with first HO2 and then
BrO in excess in an effort to identify possible
complications in the reaction conditions. At 298 K, the rate
constant was determined to be
(1.73±0.61)×10-11 cm3
molecule-1 s-1 with HO2 in
excess and (2.05±0.64)×10-11
cm3 molecule-1 s-1 with BrO
in excess. The combined results of the temperature-dependent
experiments gave the following fit to the Arrhenius
expression:
k=(3.13±0.33)×10-12
exp(536±206/T) where the quoted
uncertainties represent two standard deviations. The
reaction mechanism is discussed in light of recent
ab initio results on the thermochemistry
of isomers of possible reaction intermediates.
